kerf and jump back toward the operator.
Kickback is the result of tool misuse and/or
incorrect
operating
conditions and can be avoided by taking
proper precautions as given below:
Maintain a firm grip with both hands on
the saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line
with the blade. Kickback could cause the
saw to jump backwards, but kickback forces
can be controlled by the operator, if proper
precautions are taken.
When
blade
interrupting a cut for any reason, release
the trigger and hold the saw motionless in
the material until the blade comes to a
complete stop. Never attempt to remove
the saw from the work or pull the saw
backward while the blade is in motion or
kickback may occur. Investigate and take
corrective action to eliminate the cause of
blade binding.
When restarting a saw in the workpiece,
center the saw blade in the kerf so that
the saw teeth are not engaged into the
material. If a saw blade binds, it may walk
up or kickback from the workpiece as the
saw is restarted.
Support large panels to minimize the risk
of blade pinching and kickback. Large
panels tend to sag under their own weight.
Supports must be placed under the panel
on both sides, near the line of cut and near
the edge of the panel.
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
Blade depth and bevel adjusting locking
levers must be tight and secure before

Additional Safety Instructions for Circular Saws

This product is intended to cut wood and
wood-like products only. Dust build up
around the lower guard and hub from other
materials (plastic, masonry or metal) may
disable the lower guard operation.
Inspect the condition and quality of the
wood and remove all nails from lumber
before cutting. Wet lumber, green lumber
or pressure treated lumber require special
attention during cutting operation to
prevent kickback.

cutting, it may cause binding and kickback.

Use extra caution when sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.

▶ Lower Guard Function

Check lower guard for proper closing
before each use. Do not operate saw if
lower guard does not move freely and
close instantly. Never clamp or tie the
lower guard into the open position. If the
saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard
with the retracting handle and make sure it
moves freely and does not touch the blade
or any other part, in all angles and depths of
cut.
Check the operation of the lower guard
spring. If the guard and the spring are not
operating properly, they must be serviced
before use. Lower guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
The lower guard may be retracted
manually only for special cuts such as
"plunge cuts" and "compound cuts". Raise
the lower guard by the retracting handle
and as soon as the blade enters the
material, the lower guard must be
released. For all other sawing, the lower
guard should operate automatically.
Always observe that the guard is covering
the blade before placing the saw down on
bench or floor. An unprotected, coasting
blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of
the time it takes for the blade to stop after
the switch is released.
Hold the saw firmly to prevent loss of
control. Figures in this manual illustrate
typical hand support of the saw.
Depending upon use, the switch may not
last the life of the saw. If the switch
should fail in the "OFF" position, the saw
may not start. If it should fail while the
saw is running, the saw may not shut off. If
either occurs, unplug the saw immediately
and do not use until repaired.
This circular saw should not be mounted
